Electric APU

Ethium APU batteries are engineered specifically for Class 8 truck electric APUs. When compared with conventional AGM31 lead acid batteries, Ethium delivers unmatched capabilities.

  • 2x Available Capacity
  • 4x Longer Life
  • 2x Faster Charge
  • 2x Lighter
  • Extremely Safe and Compatible

Benefits

Significantly improved performance and driver comfort with a quick return on investment:

Extended Capacity
The ultra energy dense XL12A-3500 is capable of 275 Ah (550 Ah per application) for twice the actual available capacity when compared to leading AGM31 solutions.

Extended Life
Designed to last 3,000 deep discharge cycles maintaining close to nominal capacity with a 5 year / 1,000 cycle warranty backed by EControls.

Quick Recharge
Charges twice as fast as AGM31 with Active Voltage Control (AVC).

Lightweight
Less than half the weight of lead acid batteries: 550 Ah is only 153 lbs.

Drop-in Replacement
Fits in your existing APU battery compartment and meets your battery weight requirements.

Maintenance Free
Easy to install with no need for maintenance or replacement.
